Need a chess repertoire

In My Humble Opinion
1

First off, Mods: I’m looking more for advice/discussion about a course of action, not to play or talk about a game. I therefore put this in IMHO, not TGR.

I need to settle down on a set of openings. I’ve been drifting through my chess career dabbling in this and that opening, never really picking one. I’m strictly a 1.d4 player but I need some help with black. Against 1. e4, I have been playing the Sicilian but I need to pick one to stick with. Should I go with a Sveshnikov, Najdorf, or Scheveningen? I’ve been playing the Najdorf and playing 6…e6 against almost every response.

What about against d4? Nf6 is my choice now but I’m more or less lost after that. I like the King’s Indian but it’s a little scary for me to start flinging kingside pawns down the board like that.

FWIW, I’m a 1600 player and I play/study almost daily. While I want to play the best moves, I’d like to avoid wild, tactical play as much as possible and have only a few offshoots to memorize. I prefer promoting pawns than smashing toward the king. Also, I’m experienced and advanced enough to understand about not memorizing moves but “learning the ideas”, blah blah blah.

My policy is to play the French defense, when I’m black, against a higher-rated player. The reasoning is that the French Defense is a good opening for drawing, since it allows black to jam up the middle and build a strong kingside defense.

I do not really have a fixed opening chosen when I’m playing against lower-rated players. I played the Sicilian a lot when I was younger. These days, it seems that everybody has twenty different variations on the Sicilian memorized to about thirty moves. I’m in the market for something else.
